Given that;

Need of flour for cakes= 17 2/5 pounds

Now,

There are 4 large bags, and each one has 4 pounds.

She buys all of the large bags, she already has;

4x4=16

16 pounds. So, she only needs

17 2/5 -16= 1 2/5

=5/5+2/5

=7/5

1 2/5 pounds more, this fraction is equals to 7/5 pounds.

The small bags only contains 1/5 pounds of flour so,

7/5/1/5

=7*5/1*5

=7

Therefore, by algebra the answer will be 7 bags

According to the information in the table, the graph would look like the one in the attached image.

To graph the information in the table we must carefully observe the information. In this case, the relationship is decreasing because the number of infected is decreasing as time increases. In accordance with the above, the curve that shows this relationship is a decreasing curve.

In this case, we must locate the time on the x axis and the infected on the y axis and mark a point in the areas where the data coincide. Later we must graph a line that joins the points and our graph would be finished.

Answer: 28, 30, 32

Step-by-step explanation: The first integer is 28, the second is 30, and the third is 32. The difference from the first integer and the last integer should be 4. x is the first integer, so the equation is:

x+x+2+x+4=90

The first integer plus the second integer(x+2) plus the third integer(x+4) equals 90. Now solve.

x+x+2+x+4=90

3x+6=90

    -6  -6

3x=84

/3   /3

x=28

So the first integer is 28, second is 30, third is 32.

What is triangle ?

Triangle can be defined in which it consists of three sides, three angles and sum of three angles is always 180 degrees.

Let's call the two legs of the right triangle a and b, and the hypotenuse c. The hypotenuse is the side opposite the right angle, so in this case, we have c = 29. We also know that one of the acute angles is 71 degrees.

Using trigonometry, we can use the tangent function to find the length of the base:

tan(71) = a/b

We can solve for b by multiplying both sides by b:

b tan(71) = a

Now we can substitute c = 29 and solve for b:

b = c / tan(71)

b = 29 / tan(71)

b ≈ 8.71

Hence, The length of the base is approximately 8.71 units.

Figure ABCD is a square. If AC+BD=56, the length of AX is 28.

Since ABCD is a square, all sides have the same length, let's call it "x".

We know that the sum of the diagonals of a square is equal to twice the length of a side, so AC + BD = 2x.

Therefore, 56 = 2x, and x = 28.

So the length of AX (or any side of the square) is 28 units

The true statement is (b) Function 2 has the lowest average rate

We start by calculating the average rates of each function

The interval is given as [1, 2]

For Function 1

We have

f(1) = -3

f(2) = 3

The average rate is then calculated as

Average rate = [f(2) - f(1)]/[2 - 1]

Average rate = (3 + 3)/1

Average rate = 6

For Function 2

We have

f(1) = (1/4)^1 + 4 = 4.25

f(2) = (1/4)^2 + 4 = 4.0625

The average rate is then calculated as

Average rate = [f(2) - f(1)]/[2 - 1]

Average rate = (4.0625 - 4.25)/1

Average rate =-0.1875

For Function 2

We have

f(1) = -2

f(2) = 0

The average rate is then calculated as

Average rate = [f(2) - f(1)]/[2 - 1]

Average rate = (0 + 2)/1

Average rate = 2

The lowest average rate is -0.1875 for function 2

Hence, function 2 has the least rate

Step-by-step explanation:

You can solve this using the Pythagorean theorem which is a^2 + b^2 = c^2

Plug in your numbers so you have 2.5^2 + 1.25^2 = c^2

Simplify that down to 6.25 + 1.5625 = c^2

Add   7.8125 = c^2

Find the square root of each of them.   2.795 = c

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

The probability that Justen wins is 4/9.

The probability that Justen wins is determined by the likelihood that the highest number rolled on the two dice is a 1, 2, 3, or 4. To find this probability, we can first calculate the probability that the highest number rolled is a 5 or 6, which is what would cause Gaberil to win.

The probability of rolling a 5 or 6 on one die is 2/6, or 1/3. The probability of rolling a 5 or 6 on both dice is (1/3) * (1/3) = 1/9.

However, we also need to account for the possibility that one die rolls a 5 or 6 and the other does not.

This can happen in two ways: either the first die rolls a 5 or 6 and the second does not, or the first die does not roll a 5 or 6 and the second does.

The probability of each of these scenarios is (1/3) * (2/3) = 2/9.

So the total probability of Gaberil winning is 1/9 + 2/9 + 2/9 = 5/9.

Since there are only two possible outcomes (either Gaberil wins or Justen wins), the probability of Justen winning is 1 - the probability of Gaberil winning. So the probability of Justen winning is 1 - 5/9 = 4/9.

Therefore, the probability that Justen wins is 4/9.

The distance d between the student and the mirror is given by the similar triangles are d = 10.5 feet

If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.

Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides

Given data ,

Let the triangles be represented as ΔABC and ΔCDE

Now , they are similar triangles

The measure of AB = height of the school = 30 feet

The measure of BC = distance from the school to the mirror = 50 feet

And ,

The measure of DE = height of the student = 6.3 feet

The measure of CD = distance d between the student and the mirror

So , the corresponding sides of similar triangles are in the same ratio

On simplifying the equation , we get

BC / AB = CD / DE

And , 50 / 30 = d / 6.3

Multiply by 6.3 on both sides , we get

d = ( 5/3 ) x 6.3

d = 31.5 / 3

d = 10.5 feet

Vertical angles are angles that are opposite of each other when two lines crosses, they are congruent.

Given that;

Since vertical angles are congruent,

Angle A = Angle B

Plug in the given values

( 7x - 18 ) = ( 6x - 8)

Solve for x

7x - 18 = 6x - 8

7x - 6x = -8 + 18

x = -8 + 18

x = 10

Hence, angle A will be;

Angle A = 7x - 18

Plug in x = 10

Angle A = 7( 10 ) - 18

Angle A = 70 - 18

Angle A = 52°
